` disk and the attached parts may be made up adjust the valve to obtain any .desired action within its range. Besides these advantages, my valve construction 1s such that the valve tached to it by means on the stem and within the aperture.

4. A valve mechanism for pneumatic musical instruments, comprising a valve board, i a valve seat and opening in said board, a valve disk and stem therefor, and a support for the same comprising an apertured block through which the valve stem passes, and to Which it is yieldingly attached by means on in large quantities to be used interchangeably on valve boards as desired.

lt will he apparent that a skilled mechanic may make many changes in the specific embodiment of my invention without depart` ing from the spirit thereof. While` I have described the best form of my invention now known to me, I desire to cover in the annexed claims all modications which may tured block being held by frictional engager ment Within the valve opening.

'5. A valve mechanism for pneumatic musical instruments, comprising a valve board, a valve seat and opening in said valve board, a' valve disk and stem therefor, and a-support for the'same comprising a rectangular apertured block within the valve opening and held therein by frictional engagement That I claim is,-

1. In a valve for pneumatic musical in;I struments, a valve board provided with-a valve seat and opening, a valve disk and stem, and a support therefor, comprising a substantially rectangular block fitting Withg in the valve seat opening, and means on the 1 stem for preventing theready removal 4o l the valve disk from thel support. i 2. In a valve for pneumatic musical instruments, a valve board provided with a ,f valve seat and port, a valve disk and stem, j and a support therefor consisting of an I apertured block located Within the valvei port the valve stem passing through the said l block and being attached to it by means on l l disk passing through the block and through the aperture therein, and being provided with means for preventing the ready removal of the valve disk from the block.

6. As an article of manufacture, a valve disk for pneumatic musical instruments provided with a stem, a substantially rectangular guide on said stem and of a length less than the diameter of the valve. disk, and means on said stem for preventing the ready removal of said stem from said guide.

In testimony whereof my hand in presence of two subscribing Witthe stem and Within the a erture.
